This study focuses on investigating quantum Doeblin coefficients as a generalization of classical concepts in information theory.
The researchers define new quantum Doeblin coefficients with desirable properties and efficient computability.
Various interpretations of the quantum Doeblin coefficients are presented, including their representations as minimal singlet fractions and exclusion values.
The study also explores multiple applications of quantum Doeblin coefficients in various areas, providing improvements over prior literature in terms of generality and efficiency.
